I'm trying to make this work but it's causing a Segmentation fault. I've checked my code and I just can't find anything wrong with it. It's supposed to work like a simple calculator. And then I tried the man page for argv or argc and it says, "No manual entry for..." something like that. I mean, isn't there supposed to be one? Or do I have to update something?
I'd appreciate it if anyone would reply whatever he/she think/s that can help. Thanks in advance!

I think that this post is off-topic, but I'll help you anyway. What is the command that call to your program into your question? Why are you using argv[2][0] instead of argv[2]? Are you sure that your atof() function is working?
